Note. Not all versions referred to are available as approved. This book covers general aspects for hazardous andgeneral approved products.

SAFETY MEASURES

Warning.• EXPLOSION HAZARD.

SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2.

• EXPLOSION HAZARD.DO NOT REMOVE FUSE OR DISCONNECT POWER LEADS WHILE CIRCUIT IS LIVE.

• THE LOCAL TERMINAL MUST NOT BE USED WHEN THERE IS AN EXPLOSION RISK.

Warning.• Installation and maintenance must only be carried out by suitably trained personnel.

• HAZARDOUS AREA DESIGNATION ON THE EQUIPMENT LABEL MUST BE SUITABLE FOR THE INTENDED DUTYAND LOCATION.

• All relevant sections of this manual must be read before selecting a location.

• Safety requirements of this equipment, any associated equipment, and the local environment must be taken intoconsideration.

• The installation and use of this equipment must be in accordance with relevant national and local standards.

The transmitter end of the cable, the powersupply and any output cables must be prepared and connected as detailed in the relevant parts of this book. If the sensor hasbeen supplied unpotted, connections must also be made to the full-bore sensor terminal box or probe head (Fig. 3.1) and thenpotted on completion – see ENVIRONMENTAL PROTECTION.

3.1 Connection Requirements

3.1.1 Sensors

Caution.• Each connection MUST be insulated from all others; in particular, NO connections must be made to screens or drain

wires except as shown.

• All cable entries must be properly sealed.

• Glands must be appropriate for sealing on the cable size in use.

• Unused cable entries must be plugged.

• Electrical installation and earthing must be in accordance with relevant national and local standards.

• The transmitter and sensor are supplied as a matched system. Check serial numbers to ensure matched pair.

Warning.• Potting materials are toxic – use suitable safety precautions.

• Read the manufacturers instructions carefully before preparing the potting material.

• The remote sensor terminal box connections must be potted immediately on completion to prevent the ingress ofmoisture. For hazardous area versions – see HAZARDOUS AREA APPROVALS.

• Check all connections before potting – see ELECTRICAL INSTALLATION.

• Do not overfill the terminal box or allow the potting material to come into contact with the ‘O’ ring or groove.

• Do not let potting material enter conduit, if used.
